I have one project, it has one Swift (AppKit) App and one C++ dylib project, I don't have problem in build the dylib, but when build the UI App, there will be an error: "ld: multiple errors: file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/AppDelegate.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/AppDelegate.o'; file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/ViewController.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/ViewController.o'; file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/GeneratedAssetSymbols.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/GeneratedAssetSymbols.o' clang++: error: linker command failed with exit code 1 (use -v to see invocation)"

Clean project folder and rebuild - it won't fix I tried remove the two Swift files and added it again- it won't fix Delete DerivedData folder - it won't fix

I upgraded to Xcode 16.1 - also tried above, it won't fix

BUT: the project doesn't have any problem when build with Xcode 15

Thanks to ycc_ch, I did the stupid way to resolve the problem: created both projects with Xcode 16, and then copy the code over.

"I’ve been struggling with this issue for two weeks, and I’ve tried everything I could think of. The error I kept encountering was:

file cannot be open()ed, errno=2 path=path_to_my_project/arm64/xxxxx.o;

After a lot of trial and error, here's what finally worked for me:

Identify the files referenced in the error (in this case, xxxxx.o).
Open your Xcode project and locate the xxxxx.swift file mentioned in the error.
Rename the xxxxx.swift file to xxxxx_old.swift.
Create a new untitled file in the same folder, and give it the original name (xxxxx.swift).
Copy the code from the xxxxx_old.swift file into the newly created xxxxx.swift.
Rebuild the project. In the build log, the error should now reference the xxxxx_old.o instead of the xxxxx.o that was previously causing the issue.
Delete the xxxxx_old.swift file, then rebuild the project again.

After doing this, the error should no longer appear in the log for that class. I had to repeat this process for every file referenced in the log. In some cases, I had to apply the same steps twice for the same file for the solution to work.

Good luck and let me know if it helped.

Best regards,
